Abstract. In the field of floating wind energy large-scale wind turbine models deployed in natural environment represent a key link between small-scale laboratory tests and full-scale prototypes. While implying smaller cost, design and installation effort than a full-scale prototype, large-scale models are technologically very similar to prototypes, can be tested in natural sea and wind conditions and reduce by a consistent amount the dimensional scaling issues arising in small-scale experiments. In this framework the presented work is reporting the aerodynamic and control system assessment of a 1:15 model of the DTU 10 MW wind turbine installed on a multipurpose platform model for fish farming and energy production. The model has operated for six months in a natural laboratory and has been exposed to fully natural and uncontrolled environmental conditions. Assessment is performed in terms of rotor thrust force and power controller parameters such as rotor speed, blade pitch and rotor power as a function of incoming wind speed.

Short summary
The work focuses on the experimental validation of the design of a large-scale wind turbine model, based on the DTU 10MW reference wind turbine, installed on a scaled multi-purpose platform deployed in an outdoor natural laboratory. The aim of the validation is to assess that the behaviour of the model is respecting the targets established during the design phase in terms of structure, rotor aerodynamics and control. The outcome of the investigation ensures on the validity of the design process.
